SPECIFICATION forming part of Letters Patent No. 771,133, datedSeptember 27, 1904.

Application filed May 13, 1902.

To all whom it may concern.-

Be it known that I, OLIVER M. EDWARDS, a citizen of the United States,residing at Syracuse, in the county of Onondaga, State ofNew York, haveinvented certain new and useful Improvements in Windows, of which thefollowing is a full, clear, and exact description, reference being hadto the drawings accompanying and forming a part of the same.

This invention relates generally to improvements in windows ofrailway-cars and other structures, and has for its object the provisionof means whereby the joints between either the top or the bottom portionof the sash or between both portions and the corresponding portions ofthe frame may be bridged over by a yielding strip or strips of materialand thereby exclude dirt and cold at such portion or portions.

My invention consists, first, in combining with a cross part or portionof a frame and of a sash of a surface inclined at an angle other than aright angle to the guideway in the frame, a flexible strip of materialof a length substantially that of the inclined surface and of a width tobridge over the joint between the sash and frame, and securing meansadapted to secure the edge of the strip to the window in position forthe other edge to engage with the inclined surface and move away fromthe part to which the strip is secured when the window is closed;second, in combining with two cross parts or portions of a frame and ofa sash two inclined surfaces, each of which is at an angle other than aright angle to the guideway in the frame, of two flexible strips ofmaterial, one for each inclined surface, each of which is of a lengthsubstantially that of its inclined surface and securing means for eachof the flexible strips, each means being adapted to secure one edge of aflexible strip to the window in position for the other edge of suchstrip to engage with one of the inclined surfaces when the window isclosed and bridge over the joints between the top and bottom portions ofthe sash and frame; third, in providingaflexible strip of material witha thickened widthwise portion to aid in holding or securing such stripin position adjacent to a frame and a larged scale.

part movably mounted therein, whether such movable part is mounted toslide or swing in such frame; and it also consists in certain othernovel and useful combinations of parts, all of which will be hereinaftermore fully described, and particularly pointed out in the claims, whichform a part of this specification.

Like letters of reference wherever they occur indicate correspondingparts inall of the figures.

Figure l is an exterior view of a window, showing the bottom and topportions of a sash and window-frame with my improvements appliedthereto, the'sash and frame being broken away, as shown, to illustratethe parts shown on a larger scale than otherwise. Fig. 2 is a verticalsectional view of What is shown in Fig. 1 on line 2 2 thereof. Figs. 3and 4 are plan and cross-sectional views, respectively, of a portion ofthe flexible strip of material, which has one edge thereof thickened bythe addition of a rib lengthwise of the strip, which is arranged at oneedge thereof. Figs. 4 and 4 show in cross-section modifications of thestrip of flexible material seen in Fig. 4. Fig. 4f shows incross-section another modification of the strip of flexible materialseen in preceding figures. Fig. 5 illustrates one way of applying thestrip of flexible material to the bottom portion of the sash and of theframe, illustrating that seen in Figs. 1 and 2 on an en- Fig. 5 shows amodified form of parts seen in Fig. 5. Fig. 5 illustrates one way ofapplying the strip of flexible material to the bottom portion of thesashas, for instance, that form seen in Fig. 4. Fig. 5 also illustratesthe relation of the free edge of the strip to the sill of thewindow-frame when the sash is closed. Fig. 6 is asectional view showingthe application of a strip of flexible material to the top portion ofthe sash and frame, being that seen at the top of the win: dow seen inFigs. 1 and 2, but on an enlarged scale. Fig. 7 is a sectional viewshowing another way of applying the flexible strip having a thickenededge with a locking device added to illustrate how the sash is heldagainst creeping beyond a certain amount. Fig. 8

is an edge view of the bottom portion of the sash seen in Fig. .7,illustrating the manner of cutting the sash to receive the flexiblestrip and its securing means or holding-bar. Fig. 9 is a side view ofthe holding-bar seen in Fig. 7 with the rib thereon running lengthwiseof such bar and with the central portion broken away. Fig. 10 is across-sectional view of the holding-bar seen in Figs. 7 and 9. Fig. 11is a cross-sectional view of the strip of flexible material seen inFigs. 6, 13, and 14:. Fig. 12 is a cross-sectional view ofthe'holding-bar, also seen in Figs. 6, 13, and 14:. Fig. 13 shows amodification in the arrangement of the in clined surface relatively tothe sash and the frame, such surface being formed on a part of the sashitself. Fig. 14: is a view of a modification wherein the lower portionof an upper sash and the upper portion of a lower sash has the inclinedsurface arranged substantially as shown in Fig. 13. Fig. 15 showsacross-sectional view of one side of the frame, its guideway and thesash illustrating one arrangement of flexible strip and holding-bar seenin Fig. 7 relatively to the sash, frame, and guideway. Figs. 16, 17, and18 show another modification or embodiment of my improvement. Figs. 19,20, and 21 illustrate still another embodiment or example of myimprovement. Fig. 22 shows another form of applying the flexible stripto the bottom portion of the sash. Figs. 23 and 24c illustrate anothermodification or example of my improvement. Figs. 25, 26, and 27illustrate the application of a flexible strip having a thickenedwidthwise portion to amovably-mounted swinging part as a portion of asash or door.

In Figs. 1, 2, 5, and 6, A represents the sash, and B the frame whichreceives the sash, so as to slide therein in opening and closing thewindow. (1 represents the glass in the sash, and D the guideway in theframe in which the sash slides. In Fig. 1 the window is seen from theexterior of the structureas, for instance, from the exterior of thecar-this being done because it is preferred that the bottom of the sash,at least, shall have my improvement applied at or near the exteriorsurface thereof, so that the joint between the sash and its frame may bebridged over at or near this exterior bottom surface of the sash, asseen. If this be done at both the top and bottom portions of the sashand frame or at either one of the two places, it excludes the dirt,cinders, and cold air from the space within the guideway not actuallyoccupied by the sash, and consequently the sash can move in its guidewaywith less hindrance from the dirt and cinders than would be the case ifthe dirt and cinders had free access to the guideway.

It has become the practice to use in railway-cars movable stop-beads orholding devices on the interior of the car to hold the sides of the sashwith more or less firmness against its permanent or fixed stop-beads,which stop-beads form the guideway in the frame to receive the sash andpermit it to slide therein. Such movable stop-beads or holding devicesprovide means whereby the dirt and cold may be excluded from theguideway at the sides of the sash and at the exterior thereof by theholding action of the devices against the interior of the sash andforcing it outward against the fixed stop-beads of the guideway. It iscustomary with such holding devices to employ automatic raising means orcounterbalancing means. The latter means are employed to a considerableextent where these movable stop-beads or holding devices are not used.

Wherever counterbalancing or automatic raising means are employed,thesash creep that is, to move slowly and a little at a time in the openingdirection-and positive locking means are employed in such cases, so thatthe extent of this creeping action may be limited. This requires thatthere be left a little space between the points where the sash strikesthe window-sill and where the lock-bolt or detent engages with itskeeper to insure the movement of the sash in the closing direction farenough for the lock-bolt to always snap into its locking positionrelatively to its keeper and insure the complete closure of the window.In practice it has been found that this requires some considerable spaceto insure the full and ready closure of the window and that as aconsequence when the creep of the sash takes place there is this fullspace between the bottom of the sash and its sill for the entrance ofdirt and cold air intothe space within the guideway not actuallyoccupied by the sash and even if such dirt and air be excluded from theinterior of the car this dirt and cinders will so interfere with themovement of the sash in its guideway as many times to preclude theopening of the window and, if movable stops or holding devices are notused, to require a greater space in the guideway for the sash thanotherwise would be required. This greater space gives greateropportunities for the passage of dirt and cinders into the guideway andfrom thence into the interior of the car. Consequently it is preferableto. exclude the dirt, cinders, and cold air from the guideway itself andby so doing excluding the same from the interior of the car or otherstructure.

In Figs. 1, 2, and 5 the sash A has a projecting lip or portion a,formed in any wellknown or convenient way, which is for the purposes ofmy improvements the same as if formed integrally with the sash. Thisprojecting portion extends downwardly to nearly the bottom edge orsurface of the sash and when the sash is fully closed down to within ashort distance of the sill of the window-frame. The bottom of the sashmay be recessed, as indicated in Fig. 5, which recess extendssubstantially parallel with the portion a for substantially the width ofthesash. A strip of flexible material E is formed, pref- IIO \ strip Efirmly to the sash, and such bar and -erabl y, withathickened portionlengthwise of the strip, arranged as shown in Figs. 2, 3, 4, and 5 or asin some of the other figures of the drawings. In the form seen in Figs.2, 3, Land 5 the thickened portion 00 is arranged along one edge of thestrip, leaving its opposite edge comparatively thin. A recess is formedin the projecting portion a of the sash A to receive this rib-likeportion of the strip E, as shown in Fig. 5. A holding-bar F, of anysuitable material, preferably of metal, is adapted by its constructionto be secured to the sash and at the same time secure the screwsformsecuring means for one edge portion of the strip. This firm holding ofthe strip is necessary, and the thickened portion or rib along one edgeof this strip materially aids in holding the strip E firmly to the sash.The free and comparatively thin edge of this strip E extends outwardlyand downwardly from the sash A and at an angle to its exterior surfacethereof and also at an angle to the sill portion 6 of the window-frameB. This portion of the sill Z2 is adjacent to the guidewayin which thesash slides, and it also forms an inclined surface I), which is at anangle other than a right angle to such guideway, and this inclinedsurface extends from one side of the frame and guideway to the oppositeside thereof. The free edge of the strip E engages with the inclinedsurface 6 of this sill portion 6 of the frame B as the sash is moving inthe closing direction and slides down and along such'surfaceb, bendingfrom its substantially flat condition (seen in dotted lines in Fig. 5.)to the curved condition. (Seen in full lines in the same figure.) Whenthe sash is opened or creeps, the free and comparatively thin free edgeof the strip E slides upwardly onthis inclined surface 6; but it remainsfor a short distance in contact with such surface, thus bridging overthe joint between the bottom of the sash A and the inclined surface ofthe sill Z) of the frame B for a-corresponding distance.

It will be observed that the nearer the strip E in its flat conditionapproaches the angle of the inclined surface 5 of the sill bthe lesscurvature is given to the strip E on any given extent of movement of thesash A relatively to the sill b. This curvature given to the strip E bythe contact or engagement of its free edge with the inclined surface 6causes the free and comparatively thin edge to hug or remain in closecontact with such inclined surface, and thus it excludes dirt and airfrom the guideway'at the bottom of the sash to a greater extent thanotherwise, and this is the case whether the sashis in contact with thesill portion 6 or whether it is some little distance therefromas, forinstance, as seen in Fig. 7-and where the creeping of the sash hasbrought the lock-bolt in engagement with its keeper and the sash ispositively locked against 1 further creeping. When the strip E isapplied as shown in Figs. 5 and 7, the unsecured or free portions ofsuch strip are arranged at an angle to the exterior surface of the sash,and the comparatively thin edge of such strip in contact with theinclined surface b' offers but little opportunity for the wind to forcedirt and air under such contacting edge and along such inclined surfaceinto the guideway and thence into the interior of the car. 'The rib orthickened portion 0a of such strip E aids in holding the strip to thesash even when snow and ice form over the free edge of the strip and onthe sill b, which may occur under certain circumstances and in certainconditions of the weather, such as many times occur in practice. Ifdesired, the holding-bar F may be of dimensions to extend across thebottom of the sash, as indicated in Fig. 5, in which case the bottom ofthe sash will not be recessed at all and the projecting portion (0 alonebe provided. Also, if desired, this flexible strip may be incrosssection, as seen in Figs. 4, 4, 4, and 16, or otherwise, so long asthe free edge be left comparatively thin, as shown. In each of the abovecases the thickened portion of the strip extends lengthwise thereof andaids in securing the strip in its secured position, whether it besecured to the sash, as here shown, or to the frame or a portionthereof, as shown in some of the figures to be hereinafter described.The length of the holdingbar, whatever its shape in cross-section, willpreferably be substantially that of the width of the sash or frame towhich it may be applied; but the length may be such as is clesired tohold the strip of flexible material in place to do its intended work.Other holding or securing means than this bar F may be employed, ifdesiredsuch, for instance, as shown in Figs. 23 and 24it beingunderstood that any means which will properly hold the flexible strip inplace may be used, as desired.

- The strip of flexible material may be of different shapes incross-section than those heretofore referred to-as, for instance, asseen in Fig. 6, where a strip E of substantially the same thicknessthroughout is shown as applied to the top edge of the sash. As hereapplied the free edge of such strip E engages with an inclined surface 6on the upper cross part of the frame, as shown. A holding-bar F,

which is preferably of metal, is employed to secure the strip E to thesash A by screws, as shown, or otherwise, as desired. The strip E andholding-bar F are seen in cross-section in Figs. 11 and 12, and they areto be of the length desired. The inclined surface 5* is formed on across portion or part of the frame which is adjacent to the sash and tothe exterior surface of the same.- surface on this cross portion of theframe B serves a similar purpose to that served by the inclined'surfaceb of the sill portion Z) of.

This inclined &

the frame B. The sash A is recessed, as this case, as in Fig. 6, theinclined surface shown in Fig. 8, to receive the flat side of the stripE and the holding-bar F all as shown in Fig. 7, or the sash may berecessed, as seen in Fig. 5, to receive the upper portion of strip E(shown in Fig. 1) and the holdingbar F As shown in Fig. 5, the sash Areceives the strip E (seen in Fig. 4) and the holding-bar F screwspassing through both the strip and holding-bar to secure the strip tothe sash. The inclined surface b of the sill portion I)" of the frame Bserves a similar purpose to that served by the-surface 7/ of the sillportion 6 of the frame B. (Seen in Fig. In each case the free andcomparatively thin edge of the flexible strip first engages with theinclined surface when the sash approaches the closed position and as thesash continues to close such free edge slides along such inclinedsurface and gives a curvature to the flexible strip widthwise of thesame, which curvature tends to make the free edge press against theinclined surface with an increased force and also with an increasingextent of the surface of the strip engaging with such inclined surface.Also in each case the strip and inclined surface are so related to eachother that the sash may creep to quite an extent, and yet the strip willbridge over the joint between the sash and adjacent portion of theframe.

In Fig. 7 the same kind of a flexible strip as is shown in Fig. 5 isapplied to the bottom portion of the sash, but in a somewhat differentmanner. The general result is the same as in Fig. 5, although the angleof the strip in the flat condition relatively to the sill portion 5 ofthe frame B is somewhat different, as will be seen. The strip offlexible mate rial E is applied in a plane at an angle to the exteriorsurface of the sash A, as shown, and preferably a holding-bar Fpreferably of metal, is applied to the exterior surface of the sash andpreferably flush with its surface, as shown. This holding-bar F is seenin Figs. 9 and 10 in rear side elevation and cross-section,respectively. As here shown it has a rib-like portion f, which engageswith the thickened or rib portion of the strip E, and thereby aids inholding such strip to the sash.

A locking device X is shown in this Fig. 7, which has a lock-bolt ordetent and keeper of any well-known construction by which the sash maybe positively locked against creeping beyond the desired extent andwhich permits the sash to creep, as indicated by the space between thebottom of the sash and the sill 7)" in Fig. 7.

Instead of an inclined surface, with which the free and comparativelythin edge of the strip of flexible material engages, being formed on across portion of the frame adjacent to the sash it may be formed on thesash itself, if desired, as shown in Fig. 13. In

begins next to the general exterior portion or surface of the sash andextends in a direction at an angle to the guideway in which the sashslides other than a right angle and to like effect. The flexible strip Eis in Fig. 13 secured to a cross part of the frame, so that its freeedge engages with the inclined surface on the sash, as does the freeedge of the strips E and E in Figs. 5 and 6 and with substantially thesame result as in these figures and in Fig. 7. The simple reversal inpositions of the inclined surface 6' and the holding-bar F in Fig. 13over what is the casein Fig. 6 does not change the coacting relations ofthe inclined surfaces and free edges of the strips, but it permits stripE to be placed in such relation to the exterior surface of the sash thatany wind pressure from the cxterior of the window would tend to move thefree edge of such strip into closer contact with the inclined surface inFig. 13 instead of moving it away therefrom.

Fig. 14 illustrates a construction having the same principle ofoperation as the construction shown in Fig. 13, the only differencebeing that an upper movable sash takes the place of the cross part ofthe windowframe. E is the strip of flexible material, F is theholding-bar, and b is the inclined surface, which is on the sash Ainstead of on the sash A as in Fig. 13. The flexible strip E is securedto the sash A by the holdingbar F*, as seen. The operation is the sameas in the constructions hereinbefore described. The free edge of theflexible strip coacts with the inclined surface in substantially thesame manner in eaehcase. The inclined surfaces at the top and bottom ofthe sash in each case are adjacent to the exterior surface of the sashand are nearest each other at such exterior surface, and such surfacesseparate as they extend outward and away from such exterior surface andeach is at an angle to the guideway other than a right angle.

Fig. 15 illustrates the preferred way of applying the flexible strip E*and holding-bar F to the sash and relatively to the guideway in whichthe sash slides. (Seen in Fig. 7.) This strip E and the bar E arepreferably of a length equal to the width of the sash, and then the freeedge of such strip, which extends beyond the sash when such edge is inengagement with the inclined surface, is cut away, as seen in Fig. 15.This practically closes the open space where dirt and cold air can enterunderneath the sash, and there is practically no place left inwhich'dirt and cinders can accumulate to interfere with the properworking of the sash in its guideway.

In Figs. 18 and 14: the flexible strips and holding-bars are preferablyof a length equal to the width of the sash, so as to close the entireopening widthwise of such sash. These strips and holding-bars may bemade as desired either as to length or width, as it may be thoughtdesirable to serve their intended purposes in each individual case, thedimensions here shown being simply examples of what such parts may be,if desired.

If desired, the flexible strip may be made of the shape and dimensionsshown in Fig. 16. When thus made, the sash is preferably recessed, asseen in Fig. 17, to receive such flexible strip, which is preferablyapplied and held in position by a holding-bar, as shown in Fig. 18. Thisflexible strip E, as here shown, has its projecting free edge portionarranged at an angle to the exterior surface of the sash A", as is thecase in Figs. 1, 2, 5, and 7, and in this respect it is the same as eachof the strips in the above figures. This strip E has a comparativelythin free edge which contacts with the inclined surface 6 on the sill ofthe window-frame and is in this respect the same as in precedingfigures. This strip E also has a thickened porton, as compared with itsfree edgefwhich aids in securing the strip to the window. As here shown,such strip is applied to the sash; but it may, if desired, be applied tothe frame, as hereinbefore indicated. This thickened portion of thisstrip E in addition to aiding in securing the strip to the window alsoaids in holding the free edge of such strip into engagement with theinclined surface 6 by reason of the resistance to bending caused by thethickening of the strip widthwise thereof as the exterior surface of thesash is approached and reached, the lower outer portion of the sashserving as the fulcrum, as it were, against which the thickened portionof the strip bears when force is applied against the free edge of thestrip, tending to bend it width wise'as, for instance, by contact withthe inclined surface o of the window-sill. By giving the strip theangular shape seen in Fig. 16 the cut in the sash may be made morenearly at right angles to'the exterior surface thereof than could bedone and yet have the projecting portion of such strip at the same angleto such surface if the strip were substantially flat, as in precedingfigures, and this is an advantage, because the more acute the angleformed between the exterior surface of the sash and its bottom edge thegreater the danger of injury to such corher or apex of such angle bothin handling the sash and also from the action of the elements. In thepresent case, Figs. 17' and 18,

the same angle is preserved that there would be if the sash were notrecessed at allthat is, the angle formed by the exterior surface of thesash and the sill of the window. Again, if desired, the strip offlexible material may be made of the shape and dimensions seen in Fig.19, wherein both edges of the strip are of about equal thickness,withthe central portion, considered widthwise, thickened, as shown. Thisthickening of the strip also aids in securing the strip to the windowand also in resisting the bending widthwise of the strip by its freeedge engaging with the inclined surface of the sill of the window. Thisflexible strip E when applied as seen in Fig. 21 is of such dimensionsin cross-section as to permit of the sash being recessed, as seen inFig. 20, and where the angle formed between the exterior surface of thesash and the recess is a right angle, as seen. This strip E is held inposition by the holding-bar F, as shown in Fig. 21, and so that the freeand comparatively thin edge of such strip engages with the inclinedsurface 5'- of the sill of the frame B. The operation is the same insubstance as in the construction shown in Fig. 18. In each ofthese twofigures the strip and holding-bar is preferably of the length of thewidth of the sash, and the projecting portion of the strip will benotched or cut away to the extent required to pass the fixed or exteriorstop-beads or stops which form a portion of the guideway in which thesash slides, substantially as seen in Fig. 15. Again, if desired, a flator substantially flat strip of flexible material may be used, as seen inFig. 22, wherein this strip F is shown as being held to the sash A bythe holding-bar F, and the free edge of the strip E engages with theinclined surface 6 of the sill of the frame B. As here shown, there isthe same general action of the free edge of the strip and inclinedsurface as in other figures; but the strip E does not ofl er theresistance to the bending action, as is the case with the thickenedstrips E and E of Figs. 18 and 21. Again, if desired, a flexiblestriphaving one side portion at an angle to the other side portion, as seenin Fig. 23, may be used and, if desired, attached to the sash, also asshown, with an inclined surface arranged at an angle to the guidewayother than a right angle, which is formed on a cross portion of theframe to exclude dirt and cold at the top edge of the sash. The flexiblestrip E may, if desired, be secured to the sash by screws and washers,as indicated in Fig. 23, one of the washers F being seen in plan view inFig. 24, or any other desired means may be employed to secure such stripto the window in position for its free edge to engage with and bearagainst an inclined surface Z) and bend the strip widthwise as such freeedge moves along such inclined surface in the act of bringing the sashinto its fully-closed position. The washers F bear upon the strip E andafford a means for the screws to firmly hold the'strip to the sash A.The sash A is shown in Fig. 23 as nearly closed and in position for thefree edge of the strip E to engage with the inclined surface 6 on thecross top portion of the frame B as the sash continues its movement inthe closing direction in the guideway. This free edge of the strip E asit engages with the inclined surface 6 moves down and along the same,bending the strip widthwise, and the thick- IIO ened. central portion ofsuch strip resists this bending action, as before explained.

. The advantages attending the use of the thickened widthwise portion ofthe flexible strip of material, as heretofore explained, are largelypresent when the sash is mounted to swing in the frame instead of toslide, as in the preceding descriptions, for the reason that in eachcase this thickened widthwise portion has a similar holding effectirrespective of the direction force is applied to move the sash.

In Figs. 25, 26, and 27 there is shown a construction in which there isa frame B having part of a sash A or similarly-movable part mountedtherein by means of hinges attached to one side of such part and to theframe, so that it swings as a door swings on its hinges. The swingingsash or door part A of course closes the opening of the frame, as usual,and when such part is in the closed position it is many times desirableto exclude cold and dirt, including, of course, water, from the bottomedge thereof, or that portion which may be brought comparatively closeto the frame, but not into tight contact therewith, and this is sowhether such part has a sidewise swinging movement, as in Figs. 25, 26,and 27, or has a bodily-sliding movement, as in preceding ligures.

In Fig. 27 a flexible strip like that shown in Figs. 3 and 4: is appliedto such a swinging movablymounted part; but any desired construction offlexible strip provided with a widthwise thickened portion may beemployed that is desired so long as such thickened portion aids insecuring such strip in position to the part to which it is attached.This thickened portion may serve other functions than simply aiding inholding the strip to the part to which it is secured, as hereinbeforeexplained.

As shown in Figs. 25 and 27, the flexible strip E is applied to theexterior surface of the movably-mounted sash or door part, and aholding-bar F is preferably used, being secured in place by any desiredmeans to hold the strip E firmly in place on the part A, so as to movetherewith when such part is moved. The frame B is preferably providedwith a sill portion 7), as shown in Fig. 27, against which the free andcomparatively thin edge of the flexible strip may contact when such partis in the closed position, as seen in Fig. 27 It is to be understoodthat this free thin edge is to have any desired relation to the sill 6so long as it may serve its desired function of excluding undesirablesubstances from passing between it and such sill portion to the desiredextent, this being a matter so far as the mere holding of the flexiblestrip in position is concerned which is within the discretion of theconstructor. The form in crosssection the thickened widthwise portion isto have may be such as desired to effect the desired result. Theflexible strip may be applied to the movable part in any relationthereto that is desired so long as it has the general mode of operationherein described. These strips of flexible material may be made of anysuitable material which will give the desired degree of flexibility withthe desired resistance against bending widthwise, so that they may havetheir free edges held in engagement with the inclined surface orsurfaces with which they contact in closing the window and to bridgeover the joint between the sash and its corresponding portion of theframe.

I have found in practice that canvas cloth covered with a good qualityof india-rubber of suitable thicknesses forms a very good flexiblestrip. I prefer to place the canvas or cloth at or near the surface ofthe strip which engages with the inclined surface, because it does notstretch as readily as the pure indiarubber does. These strips may,however, be made, as desired, of any material and in any manner to meetthe individual views of the constructor. of flexible material byholding-bars which are removable by removing screws or other holdingmeans therefrom permits of 'a damaged strip being replaced by a new onewith ease and despatch, and if such strips are applied as in Figs. 1, 2,5, 6, 13, 1 1, 16, and 21 this can be done without marring or injuringthe looks of the structure at points where such injury to or marring ofpaint or other portions connected therewith would be readily seen. Thisapplication of the strips permits of their removal when the car is runinto the shop for revarnishing or a general overhauling, and thus permitsuch revarnishing or refinishing to be done without interference from ordanger of injury to such strips and also of new strips being appliedwithout making The application of these strips new holes to receive thefastening means, as

' may be such as is desired so long as it is other than a right angle tothe guideway and provides means with which the free edge of the flexiblestrip may engage and move, as hereinbefore explained, and in certaininstances such free edge is caused to move away from the part to whichthe strip is secured as the window is closing and bend such strip moreor less widthwise and give a more or less intimate contact of suchportion of the strip with the inclined surface with which it engages.The relation of this free edge portion of the strip to the inclinedsurface is more or less angular and not parallel, so that as the freeedge engages with the inclined surface this portion of the strip maymove relatively thereto, as herein shown and describedthat is, such freeedge may engage and move down the inclined surface away from the sash towhich the strip is secured, as shown in Figs. 5, 5, 7, 5, 18, 21, 22,23, 27, and the lower portions of Figs. 1, 2, and 25, or may engage andmove along the inclined surface, as shown in Figs. 6, 13, 14, and theupper portions of Figs. 1 and 2.

I have herein shown and described different constructions, and otherswill naturally be suggested to mechanics by the foregoing. and thereforeI do not wish to limit myself to the several examples or embodiments ofmy invention herein shown and described, but desire that all examples orembodiments which have the same principles of operation as herein setforth shallbe included therein as of this invention.

The terms top and bottom have been used herein because they aptlydescribe the portions of the sash or frame to which they are applied,and it is to be understood that each applies to the same portion whetherthe sash moves vertically or horizontally in the frame or in anydirection between these two-- that is, the term top refers to the partof the sash in advance when opening the window and the term bottom tothe part in advance when closing the same.

I have herein shown the sash and frame as broken centrally thereof, andit is to be understood that either of the constructions seen in Figs. 13and 14 may be substituted for the construction seen at the top portionof the window in Fig. 2 or that the construction shown in Fig. 7 may besubstituted for that shown at the bottom portion of Fig. 2, the topportion remaining the same or not, as desired. Again, the constructionshown in Fig. 23 may be substituted for the top portion in Fig. 2 andthat seen in either Fig. 5 or that seen in Fig. 18 for the bottomportion of Fig. 2, and so on, as the constructor sees fit, accordinglyas his judgment may dictate.
